gil44 Posted May 13, 2016 Share Posted May 13, 2016 HelloI recently updated the kernel of Jessie on the Od-C2:# uname -aLinux odroidc2 3.14.65-odroidc2 #33 SMP PREEMPT Sat Mar 26 14:50:37 CET 2016 aarch64 GNU/LinuxConsequently, with this new environment, the wifi connection fails:# iw wlan0 scannl80211 not found.when started mannually, the wpa_supplicant starts +/-:# wpa_supplicant -B -i wlan0 -O /var/run/wpa_supplicant -c /etc/wpa_supplicant.confSuccessfully initialized wpa_supplicantBut:# ifup wlan0wpa_supplicant: /sbin/wpa_supplicant daemon failed to startrun-parts: /etc/network/if-pre-up.d/wpasupplicant exited with return code 1Failed to bring up wlan0.# iwconfig returns:eth0 no wireless extensions.ip6tnl0 no wireless extensions.sit0 no wireless extensions.lo no wireless extensions.

(The wired internet-connection is full functional)I dig in many forums but I didn't found nothing similar... Seems to be a bug ? Link to comment Share on other sites More sharing options...
Igor Posted May 13, 2016 Share Posted May 13, 2016 Which kernel did you use before? You were using some other image and you are only using our kernel? Link to comment Share on other sites More sharing options...
gil44 Posted May 13, 2016 Author Share Posted May 13, 2016 I was using your kernel before the update, that was 100 % wifi-functional Link to comment Share on other sites More sharing options...
Igor Posted May 13, 2016 Share Posted May 13, 2016 Probably some bug. There were many updates on our and their side ... and C2 is months away from stable. Perhaps some stupid idea - remove /etc/udev/rules.d/70-persistent-net.rules and try again. Link to comment Share on other sites More sharing options...
gil44 Posted May 13, 2016 Author Share Posted May 13, 2016 Hi! Thanks for your suggestion! "...and C2 is months away from stable" , a sweet euphemism : ). Unfortunately, removing the persistent rules has no effect on the wifi... I will build again a new OS with your kernel, and avoid to change again to the c2 version!

Igor Posted May 13, 2016 Share Posted May 13, 2016 Can you point me to 100% working kernel, which version of kernel and armbian build? Link to comment Share on other sites More sharing options...
gil44 Posted May 16, 2016 Author Share Posted May 16, 2016 Hello Thank you for your attention and sorry for the delay... family time.. The image before that was working fine was the 'Armbian_5.06_Odroidc2_Debian_jessie_3.14.65_desktop' version. To be installed, the root partition was transferred with the nand-sata-install script to an USB 3.0 storage device and the depository address was changed like suggested here somewhere, replacing 'http://httpredir.debian.org/debian' to 'http://ftp.uk.debian.org/debian' in the /etc/apt/sources.list file. Recently, after an upgrade, the wifi has been totally lost. I built today a new image from the last version of your software (http://mirror.igorpecovnik.com/Armbian_5.10_Odroidc2_Debian_jessie_3.14.67_desktop.7z), transferred the root partition of the SD to an USB 3.0 device with the incorporated nand -script, made an update/upgrade (keeping the http://httpredir.debian.org/debian address), installed different programs like the navit and gps-daemon and everything works now (again!) like a charm. So... It was well a bug before... A very good day-end! 1 Link to comment Share on other sites More sharing options...
